MIT team proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

At cruising altitude, airplanes emit a steady stream of NO x into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. Previous research has shown that the generation of these chemicals due to global aviation results in 16,000 premature deaths each year. increase in block fuel burn. Speth, Sebastian D.

UN report projects that increasing use of HFCs likely to have a significant climate impact by 2050; equivalent to current total annual emissions from transport

Green Car Congress

The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). Climate and the Ozone Layer. Source: UNEP. Click to enlarge.

IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. Total anthropogenic GHG emissions were the highest in human history from 2000 to 2010 and reached 49 (±4.5)

ICCT study finds that transitioning to low-GWP MAC refrigerants in China could avoid up to US$150B in costs

Green Car Congress

Among the findings of the report, “HFC-134a phase-out in the Chinese light-duty motor vehicle sector”, was that, considering the social cost of CO 2 e, up to 1 trillion RMB in costs (US$150 billion) required to address climate change could be avoided through 2050 by transitioning to low-GWP alternative MACs.

European Parliament calls for fast action to cut non-CO2 climate forcers

Green Car Congress

The European Parliament is calling for fast action to reduce non-CO 2 climate forcers including black carbon soot, hydrofluorocarbons (HFCs), methane, and ground-level ozone, which together are responsible for nearly half of climate forcing. Even cutting CO 2 emissions to zero today will not produce cooling for a thousand years.

EPA and DOT issue final Phase 2 GHG and fuel efficiency rulemaking for medium- and heavy-duty trucks

Green Car Congress

These standards will result in significant GHG emissions reductions and fuel efficiency improvements across all of these vehicle types. For example, when the standards are fully phased in, tractors in a tractor-trailer will achieve up to 25% lower CO 2 emissions and fuel consumption than an equivalent tractor in 2018.

Tata Motors and MAHLE partner to develop a prototype Secondary Loop Mobile Air Conditioning System on a vehicle

Green Car Congress

This is in contrast to the conventional mobile AC system, where the cabin air is directly cooled by the refrigerant HFC-134a, which is ozone safe but has a high GWP. This project envisages use and trial of environment friendly, low global warming potential (GWP) refrigerants HF01234yf (ASHRAE A2L) and HFC-152a (ASHRAE A2).
